OptiMate CABLE O-40s Weatherproof SAE socket, panel mount

The OptiMate O-40s is a compact, weatherproof panel mount extension socket designed to establish a permanent, clean SAE power point through any flat exterior panel or bodywork. Featuring a shorter 15 cm (6″) cable design, it is perfectly tailored to connect seamlessly with pre-existing factory wiring configurations—such as the standard under-seat SAE leads on Harley-Davidson motorcycles—without leaving unmanaged wire clutter. Once installed, it creates a rigid, flush-fitting exterior portal to easily hook up smart battery chargers, maintainers, or 12V accessories.

Features and Benefits

• Clean bulkhead integration — The heavy-duty connector body is engineered to fit a standard 18 mm (23/32”) drilled hole, creating a secure, low-profile exterior interface that eliminates loose dangling wires.

• Tailored powersport length — The compact 15 cm (6″) cable length provides just enough clearance to bridge internal vehicle harnesses to the frame, making it ideal for modern motorcycles, ATVs, and side-by-sides.

• Easy front-mount installation — Designed with a front-inserting body and a secure, heavy-duty rear fastening locknut, providing a solid, vibration-proof grip on any panel from 1 mm (0.040″) thickness upward.

• Bi-directional SAE pass-through — Utilizes an industry-standard 2-pin SAE connector on both ends, acting as a direct weatherproof portal to route charging current in or accessory power out.

• Reliable current delivery — Safely rated for a continuous 5A average current draw and up to a 7A maximum threshold, fully supporting standard electronic accessories and maintenance chargers.

• 18 AWG / 0.82 mm² wiring — Built with high-purity copper strands shielded by rugged SPT-2W insulation to maximize structural durability and defend against sharp sheet-metal panel edges.

• Weatherproof inline sealing — Outfitted with a premium, integrated rubber inline sealing cap and protective shroud to completely isolate and lock out driving rain, mud, dust, and corrosive road grime from the SAE plug face.

• Rated for –40 °C/°F — Constructed from ultra-premium materials optimized for severe weather exposure; the thick insulation remains fully pliable, flexible, and crack-resistant even in deep sub-zero freezing winter conditions.
